CONTAINER.

Application led June 19, 1922. Serial No. 569,344.

To all whom t may concern:

Be it known that I, HARRY C. WEIs, a citizen of the United States, and resident of Monroe, county of Monroe, Michigan, have invented a certain new and useful Improvement in Containers, of which the following is a specification.

This invention relates to containers in general, but more particularly to those made of sheet material, such as paper orother fibrous material, and more especially to those which are round or cylindrical in character, having a fixed head at the bottom or at one end thereof, and a removable cap at the top or other end.

Generally stated, the object of the invention is to provide a novel and improved construction whereby either the head, or either the top or the bottom, may be constructed in a strong and an effective manner, with as little expense as possible, and in a way that will ensure against leakage when the container is used for holding liquids.

lt is also an object to provide certain details and features of construction tending to increase the general efliciencypandl the desirability of a container of this particular character.

To the foregoing and other useful ends the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawings in which- Figure 1 is a side elevation of a container involving the principles of the invention.

Figure 2 is a vertical section of said container. y

Figure 3 is a view looking down on the cap before the same is completed, showing the fibrous material turned in to receive the other elements of the cap.

Figure 4 is a vertical section on line 1f-4. in Figure 3, showing in addition the two dises which form the head or top wall of the cap.

As thus illustrated, the container body 1v is of cylindrical form, and is made of papery or other fibrous material or any suitable sheet material. The lower edges of the cylinder are turned in to form a flange 2, and the upper and lower discs 3 and l are clamped together with this flange between them, in the manner shown, and compressed together with glue or other adhesive to make them adhere to each other and to the said flange, thus forming a two-ply solid bottom wall for the cylindrical container. The cap 5 is cylindrical and fits over the open top or open end of the container, and the head or top wall of this cap is made in the same manner-that is to say, it is made exactly like the bottom just described for the container. In other words, said cap has its upper edges turned in to form a flange 6, and the upper and lower discs 7 and 8 are clamped together with said flange between them, and are provided with adhesive to make them adhere to each other and to the flange. If the container is to be made of paper or other fibrous material, it can be formed from paper tubing of any suitable character, such as the spiral tubes employed for various purposes. The container, when completed, can be coated with paraffinor anything else that will make it smooth and waterproof in character, and the cap may be treated in the same manner. ln this way, and by| this simple construction, a strong and serviceable container is obtained, which is suitable for holding liquids or for other purposes.

The manufacturing methods, and the instrumentalities to be employed, in making a container of this character, are simple, it will be understood, inasmuch as the turning in of the edges of the cylindrical walls,

either of the container or of the cap, is easily done, and the discs of paper or other suitable material are then easily applied in the manner described.

Therefore, as shown and described, at both the top and the bottom of the con tainer, the inner disc is perfectly flat when inserteth and the edges of this disc impinge against the cylindrical side walls in the manner shown and described. The outer disc is crowded into place, forming a countersunk head at each end of the carton, and there is nothing in the bead or rounded portion formed between the flange 6 (or the flange 2) and the` side wall, for the inner dise is flat when inserted and is cut large enough to fit tightly within the cover or the carton itself.

Obviously', in the construction shown and described, the meeting surfaces of the discs 3 and 4 are in the plane of the flange 2, and the meeting surfaces of the disc 7 and 8 are in the plane of the flange 6, and in both cases the outer edges of the two discs are above and below the plane of the flange.

Thus the edges of the inner and larger disc not only impinge upon the inner surface of the cylindrical container` but it is also true that these edges are held in this position, so that this impingement is maintained by the adhesion between the two discs, and by the flange, 2 or 6, inserted between the two discs, and to which the edge portions of the discs adhere, whereby the smaller and outer disc is countersunk and has its edges in tight engagement with the bead formed in the manner shown between the sides of the container and the horizontal flange. Thus two perfectly flat discs .are employed in the making of the end wall for either' the container or the cap thereof.

Thus with the construction shown and described, which is illustrative of the invention, a two-ply bead 9 is formed around the end of the cylinder formed by the walls l, or by the walls 5, and the construction prevents any portion of the upper disc 3 from extending downward into this bead, whereby the bead may be formed by folding and creasing and compressing the sheet material upon itself, and bv this is meant that the material is folded around and inwardly in such a manner as to form a bead composed entirely of the material of the cylindrical side walls, so that the material which is folded inwardly and compressed to form the bead is directly opposed by the material of the cylindrical side walls, without anything between them, thus affording opportunity for the expeditious and satisfactory assembling of the different parts, and the formation of a rounded bead of the requisite and desired character.

As plainly shown in Fig. 2, the inner discs 3 and 8 are slightly sprung out of their normal or originally flat condition.

and are thus dished at theiredges, so that the two discs 3 and 4; are flared apart at their outer edges, bracing each other, back to back` so to speak` against displacement, and this is also true of discs 7 and 8, as shown and described. In this way the discs 3 and 4 are flared apart to provide an inwardly tapering space between them for the flange 2, and the discs 7 and S are flared apart to provide an inwardly tapering space between them for the flange G, as shown and described. Thus, the difference in diameter between the discs 3 and 4 is substantially equal to the thickness of the bead 9, less the thickness of the outer Walls l of the container. The difference between the two discs 7 and 8 is of a similar character. In this way, the disc 3 tightly fits the bore or inner surface of the cylindrical side walls l, and disc 8 tightly lits the interior of the walls 5, each disc being dished slightly, with its concave side facing the interior of the container, as shown and described, when the discs are compressed together to clamp the flange between them. It will also be seen that the discs l and 7 are slightly dished, the concave side of each disc facing outward, thus contributing to the flared apart relation of the discs and 4, and to the flared apart relation of the dises 7 and 8, to form the inwardly tapering space in each case for the flange 2 or the flange (i, by which the discs are held in place, whereby tight joints are provided to form a tight container. The dishing of the disc 3 is plainly shown at 10 in Fig. 2, and dishing of the disc L is plainly shown at 1l. forming straight bevel portions, in the same figure of the drawings. In a similar way, the dishing of the disc 7 is plainly shown at l2. while the dishing of the disc S is plainly shown at 13, thus illustrating how the discs are flared apart at their edges when they are compressed together in the manner shown and described. Tn this way, very obviously, as shown, the discs are braced and held against upward or downward displacement by their beveled edge portions in engagement with the container body.

What T claim as my invention is- In a container, a cylinder having its edge folded upon itself to form a bead and an inwardly projecting annular flange, a flat disk of slightly greater diameter than the inside of said cylinder mounted in said cylinder immediately adjacent the inside o l said flange, and a second flatl disk of slightly greater diameter than the inside of said bead mounted within said bead immediately adjacent the outside of said flange, said.

disks being compressed together and against said flange, whereby each of said disks is slightly dished to accommodate the flange and cause the edges of the disks to form a-tight joint with the cylinder.
